DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a receiving device,
In particular, the present invention relates to a receiving device that can easily obtain audio data such as a song as a program broadcasted by a radio broadcast or a television broadcast, or image data such as a movie.

[0002]

2. Description of the Related Art For example, a program broadcast in a radio broadcast or the like can be received by a radio receiver.

[0003]

By the way, in a radio broadcast, if a program is a song program, a song as the program is broadcast (transmitted) as a broadcast signal. Here, the broadcast signal may include the sound of an announcer (disc mug), sound effects, jingles, and the like. Therefore, the song itself (for example, a CD (Compact Disc) for sale, etc. Anything that does not include a sound other than the music (hereinafter referred to as formal music data as appropriate) can be said to be related to the broadcast signal, and can be said to be related data.

[0004] A user listens to a tune broadcast in a radio broadcast (other than the tune, for example, one containing noise such as the sound of an announcer (hereinafter referred to as broadcast tune data as appropriate)) with a radio receiver. Sometimes, I like the song and want it. In this case, there is a method of purchasing a CD in which the song (official song data) is recorded at a store.

[0005] However, in order to purchase a CD in which a song desired by the user is recorded (stored), the user needs to know the title, the name of the singer, etc., and the song is, for example, a new song. In many cases, the user does not know the title or the like. In a radio broadcast, an announcer generally introduces the title of a song, a singer's name, and the like.

Therefore, in the so-called visible radio broadcasting which has started broadcasting in recent years, in addition to the broadcast of a broadcast signal as an original program (hereinafter, referred to as a main broadcast as appropriate), additional information added to the broadcast signal is added. Is broadcast by data broadcasting. The additional information by data broadcasting may include the title of the song and the name of the singer, and therefore, the user can recognize the title and the name of the singer by looking at the display of the additional information.

[0007] However, additional information broadcast in a visible radio broadcast may be overlooked by the user or may not be memorized, or the relevance to the broadcast may be lost.

The present invention has been made in view of such a situation. For example, audio data such as music as a program broadcasted by radio broadcasting or television broadcasting, or image data such as a movie, etc. It is intended to be easily available.

Then, as shown in the flowchart of FIG. 10, first, in step S11, the operation unit 3
It is determined whether or not 1 has been operated to output display data. If it is determined that such operation has been performed, the process proceeds to step S12, where the selector 63 reads out the display data stored in the memory 63A, The data is supplied to the display device 30 via the extension unit 70, and the process returns to step S11.
As a result, the display device 30 displays, for example, a jacket photo, an artist photo, a title, a singer name, and the like of the song currently being broadcast in the main broadcast.

In step S11, the operation unit 3
If it is determined that No. 1 has not been operated to output the display data, the process proceeds to step S13, and it is determined whether the bookmark has been operated on the operation unit 31. Step S
In 13, when it is determined that the operation unit 31 has performed a bookmark operation, that is, when the user is interested in the song broadcasted in the main broadcast (interesting), the user can put a bookmark on the song, so to speak. In step S14, the selector 63 reads out the bookmark data, the sample sound, the compressed encryption data, and the like stored in the memory 63A, supplies them to the storage 64 and stores them, and returns to step S11. That is, the storage 64 stores (records) the bookmark data, the sample sound, the compressed and encrypted data, and the like of the song broadcasted in the main broadcast when the operation unit 31 performs the bookmark operation.

Here, as described above, in the memory 63A, the content for data broadcasting is updated every time the broadcasting of one song in the main broadcasting is completed, so that the sample voice or compressed encrypted data of a certain song is reproduced. Are stored in the storage 64 when the operation section 31 is bookmarked during the main broadcast of the song.
If the bookmark operation has not been performed, the user terminal 3
Deleted from

On the other hand, in step S13, the operation unit 3
If it is determined that No. 1 has not been bookmarked,
Proceeding to step S15, it is determined whether or not the operation unit 31 has been operated to output a sample sound. If it is determined in step S15 that the operation unit 31 has been operated to output the sample sound, the process proceeds to step S16, where the reproduction control unit 67 reads the sample sound stored therein from the storage 64, and The data is supplied to the speaker 29 via the data expansion unit 69 and the D / A converter 28, and the process returns to step S11. As a result, the sample sound is output from the speaker 29.

Here, even if the compressed encrypted data for a certain song is stored in the storage 64 by performing a bookmark operation on the operation unit 31, the user can determine what song the song is in. I sometimes forget if I was warm. Therefore, in such a case, by reproducing and listening to the sample sound as described above, it is possible to remember what kind of music the music was.

On the other hand, in step S15, the operation unit 3
If it is determined that No. 1 has not been operated to output the sample voice, the process proceeds to step S17, and it is determined whether or not the operation unit 31 has performed a download operation requesting the download of the decryption key. If it is determined in step S17 that the operation unit 31 has been downloaded,
Proceeding to step S18, the download processing section 65 performs a decryption key download process.

That is, for example, in the EMD server 5, the file of the decryption key of the compressed / encrypted data of certain official music data is managed using the ISRC of the official music data as the file name. The EMD link manages the official song data.
Assuming that the host name of the D server 5 is represented, the download processing unit 65 sets the EMD link of the bookmark data stored in the storage 64 as the host name and sets the ISRC of the
Configure RL. Further, the download processing unit 65
By controlling the modem 32 based on the URL, a communication link with the EMD server 5 is established, the personal information is read from the personal information storage unit 66, and transmitted to the EMD server 5 together with a request for a decryption key.

When receiving the request for the decryption key and the personal information, the EMD server 5 performs a charging process based on the personal information and transmits the requested decryption key to the user terminal 3. In the user terminal 3, the decryption key transmitted from the EMD server 5 in this way is received by the download processing unit 65 via the modem 32.

Upon receiving the decryption key, the download processing section 65 proceeds to step S19, supplies the decryption key to the storage 64 for storage, and returns to step S11.

If the bookmark data is not stored in the storage 64 when the download operation is performed on the operation unit 31, the user terminal 3 executes step S
Instead of performing the processing of 18 and S19, for example,
This is output from the speaker 29 or displayed on the display device 30.

On the other hand, in step S17, the operation unit 3
If it is determined that No. 1 has not been downloaded,
Proceeding to step S20, it is determined whether or not the operation unit 31 has been operated to reproduce a song (hereinafter, appropriately referred to as a reproduction operation). If it is determined in step S20 that the operation section 31 has been operated for reproduction, the process proceeds to step S21, in which the reproduction control section 67 starts reproduction of the music, and returns to step S11.

That is, the reproduction control unit 67 stores the storage 64
, The compressed encrypted data and the decryption key stored therein are read and supplied to the decryptor 68. The decryption unit 68 decrypts the compressed and encrypted data from the reproduction control unit 67 using the decryption key from the reproduction control unit 67, and supplies the decrypted data to the data decompression unit 69. In the data decompression unit 69, the decoded data from the decoder 68 is decompressed into official music data, and supplied to the speaker 29 via the D / A converter 28. Thereby, from the speaker 29, for example,
The same tune as when a CD is reproduced is output.

The data decoded by the decoder 68 and the data decompressed by the data decompression unit 69 are
It is possible to output from an output terminal (not shown) and to perform recording and reproduction with an external device.

On the other hand, in step S20, the operation unit 3
If it is determined that No. 1 has not been played, the process returns to step S11.

When the storage section 64 does not store the compressed and encrypted data or the decryption key when the operation section 31 is operated for reproduction, the user terminal 3 performs, for example, To that effect,
The signal is output from the speaker 29 or displayed on the display device 30.

When a plurality of sets of the compressed and encrypted data and the decryption key are stored in the storage 64 when the operation section 31 is operated for reproduction (when the operation section 31 is operated to output the sample sound). The same applies when a plurality of sample voices are stored in the storage 64). For example, a list of song titles and singer names corresponding to the plurality of compressed and encrypted data is displayed on the display device 30. Thus, the user can select which compressed and encrypted data is to be reproduced. Note that the title of the song corresponding to the compressed and encrypted data can be recognized by referring to the bookmark data stored in the storage 64.

As described above, the transmitting apparatus 1 arranges the bookmark data necessary for obtaining the decryption key for decrypting the compressed and encrypted data of the music broadcasted in the main broadcast, and transmits the data for data broadcasting. Is configured, and while transmitting the main broadcast data, bookmark data necessary for obtaining a decryption key for decrypting the compressed and encrypted data of the song broadcasted in the main broadcast data is arranged. The transmitted data broadcast data is transmitted a plurality of times. On the other hand, in the user terminal 3, when the main broadcast data and the data broadcast data are received and the operation unit 31 performs a bookmark operation, the bookmark data included in the data broadcast data received at that time is stored in the storage 64. Is done.

Therefore, the user can easily obtain the official music data for the desired music based on the bookmark data.

In the above case, in the data broadcast, the compressed and encrypted data is broadcast and the EMD server 5
Requires a decryption key to be used for the decryption. However, in the data broadcasting, the compressed encrypted data is not broadcasted (but may be broadcasted), and the compressed encryption data is transmitted to the EMD server 5. It is also possible to request a set of data and a decryption key for decrypting the data. Alternatively, it is also possible to request the EMD server 5 for unencrypted official music data.
